Hilary Duff Dons Black Bikini On Set Of New Music Video

"Lizzie McGuire" star Hilary Duff is all grown up and rocking a black bikini.

The actress/singer donned the stunning number while on set of a new music video for a track off her upcoming album.

The 26-year-old, who rose to fame as a teen Disney channel icon and later went on to release a series of pop albums, took a break from the recording industry after the release of her last record in 2008. She reportedly returns from her hiatus with a more mature, alternative sound, which she has worked on with Grammy-nominated artist of the moment, Ed Sheeran.

“I think it’ll be cool,” Sheeran told MTV of the upcoming album.“She’s been gone for so long living family life that I think there are a lot of fans waiting for something new.”

Duff wed NHL player Mike Comrie in 2010, and while the couple is now separated, they still spend time together with their 2-year-old son, Luca Cruz Comrie.

Duff recently shared artwork from the upcoming record with her fans via Instagram:

“It feels good to be in the studio. It feels good to be talking about my last few years -- the high points and the low points,” Duff told MTV News in June. “I really just want to be honest and be an open book for my fans to know where I’ve been and what I’ve been doing, how I feel and all that good stuff."
